Software Center performance

Question

After migrating all our active 2007 packages to 2012, we have approximately 500 deployments (125 packages with install, uninstall, reinstall and repair programs). Software Center takes around 4-5 minutes to populate which is 2-3 times longer than RAP in
2007. Is this to be expected or do we have a performance issue?

Many thanks.
From _SCClient_xx.log I can see that it is the wmi query for CCM_Program that is the culprit.
Logentry: "Executing WMI query: Select * From CCM_Program   (Microsoft.SoftwareCenter.Client.Data.WmiConnectionManager at ExecuteQuery)" takes roughly 2 minutes and it runs at least twice every time Software Center is refreshed.
Running:
get-date;$progs = Get-WmiObject -namespace "root\ccm\ClientSDK" -query "Select * From CCM_Program";write-host ("programs: {0}" -f$progs.count);get-date
in powershell I confirmed that it is the wmi query itself which is taking its sweet time. It takes roughly 2 minutes for 520 programs on a freshly installed beefy laptop.
In comparison,
$UIResManager = New-Object -comobject "UIResource.UIResourceMgr";get-date;$progs = $UIResManager.GetAvailableApplications();write-host ("programs: {0}" -f$progs.count);get-date
Only takes about 20-30 seconds.
And the webservice we used on 2007 was based on this query:
get-date;$progs = Get-WmiObject -namespace "root\ccm\policy\machine\actualconfig" -query "Select * From CCM_SoftwareDistribution";write-host ("programs: {0}" -f$progs.count);get-date
Which takes less than a second to run...SMH
